From e7bb1edf97c276657286a57bd6d9f9607a3bf745 Mon Sep 17 00:00:00 2001 From: Tyler Goodlet Date: Wed, 5 Mar 2025 11:34:36 -0500 Subject: [PATCH] Repair/update `stackscope` test Seems that on 3.13 it's not showing our script code in the output now? Gotta get an example for @oremanj to see what's up but really it'd be nice to just custom format stuff above `trio`'s runtime by def.. Anyway, update the `.devx._stackscope`, - log formatting to be a little more "sclangy" lookin. - change the per-actor "delimiter" lines style. - report the `signal.getsignal(SIGINT)` which i needed in the `sync_bp.py` with ctl-c causing a hang.. - mask the `_tree_dumped` duplicator log report as well as the "dumped fine" one. - add an example `pkill --signal SIGUSR1` cmdline. Tweak the test to cope with, - not showing our script lines now.. which i've commented in the `assert_before()` patts.. - to expect the newly formatted delimiter (ascii) lines to separate the root vs. hanger sub-actor sections. --- examples/debugging/shield_hang_in_sub.py | 6 +- tests/devx/test_tooling.py | 33 ++++++----- tractor/devx/_stackscope.py | 73 ++++++++++++++++-------- 3 files changed, 69 insertions(+), 43 deletions(-) diff --git a/examples/debugging/shield_hang_in_sub.py b/examples/debugging/shield_hang_in_sub.py index 3cc084d..5387353 100644 --- a/examples/debugging/shield_hang_in_sub.py +++ b/examples/debugging/shield_hang_in_sub.py @@ -39,7 +39,6 @@ async def main( loglevel='devx', ) as an, ): - ptl: tractor.Portal = await an.start_actor( 'hanger', enable_modules=[__name__], @@ -54,13 +53,16 @@ async def main( print( 'Yo my child hanging..?\n' - 'Sending SIGUSR1 to see a tree-trace!\n' + # "i'm a user who wants to see a `stackscope` tree!\n" ) # XXX simulate the wrapping test's "user actions" # (i.e. if a human didn't run this manually but wants to # know what they should do to reproduce test behaviour) if from_test: + print( + f'Sending SIGUSR1 to {cpid!r}!\n' + ) os.kill( cpid, signal.SIGUSR1, diff --git a/tests/devx/test_tooling.py b/tests/devx/test_tooling.py index 3e48844..4e8a460 100644 --- a/tests/devx/test_tooling.py +++ b/tests/devx/test_tooling.py @@ -15,6 +15,7 @@ TODO: ''' import os import signal +import time from .conftest import ( expect, @@ -47,41 +48,39 @@ def test_shield_pause( ] ) + script_pid: int = child.pid print( - 'Sending SIGUSR1 to see a tree-trace!', + f'Sending SIGUSR1 to {script_pid}\n' + f'(kill -s SIGUSR1 {script_pid})\n' ) os.kill( - child.pid, + script_pid, signal.SIGUSR1, ) + time.sleep(0.2) expect( child, # end-of-tree delimiter - "------ \('root', ", + "end-of-\('root'", ) - assert_before( child, [ - 'Trying to dump `stackscope` tree..', - 'Dumping `stackscope` tree for actor', + # 'Srying to dump `stackscope` tree..', + # 'Dumping `stackscope` tree for actor', "('root'", # uid line + # TODO!? this used to show? + # -[ ] mk reproducable for @oremanj? + # # parent block point (non-shielded) - 'await trio.sleep_forever() # in root', + # 'await trio.sleep_forever() # in root', ] ) - - # expect( - # child, - # # relay to the sub should be reported - # 'Relaying `SIGUSR1`[10] to sub-actor', - # ) - expect( child, # end-of-tree delimiter - "------ \('hanger', ", + "end-of-\('hanger'", ) assert_before( child, @@ -91,11 +90,11 @@ def test_shield_pause( "('hanger'", # uid line + # TODO!?
